I had an extremely large lipoma removed from my upper back 16 days ago. The surgeon told me I would come home with a drain tube, but whoever closed for him failed to include it. 2 weeks later, i still have fluid, swelling, deep knots and pain on one side. The incision leaks a bit at one corner. I use cold packs mostly, but have tried heat. I used an antibiotic ointment. I saw the doc last friday. He seems unconcerned.
